Metal hydride TiH2 powders were treated by mechanical milling(MM). The structure and morphology of TiH2 powders milled for different periods were characterized by X-ray diffraction(XRD)and scanning electron microscopy(SEM). The lithium storage characteristics of carbon coating TiH2 were studied by galvanostatic charge and discharge tests. Results showed that the particle sizes of TiH2 powders were reduced significantly by MM and electrochemical reaction activity of TiH2 electrodes were improved after carbon coating. The TiH2/C electrode milled for 9 h showed the best electrochemical performance with a high discharge capacity of 1 226.9 mA·h/g at the first discharge cycle. From the second cycle, the TiH2/C electrode milled for 9h demonstrated good cycle stability with a high capacity retention of 72.9% after 50 cycles and displayed a discharge capacity of 222.5 mA·h/g after 50 cycles, it was 60.7 mA·h/g higher than that of the non-milled TiH2 electrode.
